BEST FOR: Water-based recreation.
THE TEST: The view is so hi-res through the Guide Extremes’ dark gray polarized lenses, I double-checked with Revo to confirm that they’re polycarbonate, not glass. In terms of optics, this is some drastic plastic. It also offers what may be the world’s best water-shedding coating. The styling is man-size, with lenses that cover high and wide and snap-on side shields to seal out peripheral glare. More important than styling: the Guide Extremes are made to stay put, with sticky rubber where you need it at the nose and temples. A smart detachable lanyard keeps your shades close when you’re not wearing ’em.
THE VERDICT: Boaty made beautiful.
